IMPROVEMENT IN MACHINES FOR BENDING BARS OE METALL titre Srigchulerifatta tu in tigrse'ftittrrs ntrnt :mh mating gaat nf tige time.

Bc it known that I, OBED LONG, of Joliet, in Will count-y, and State ofIllinois, have invented a new and useful Machine for Bending or FormingRods or Bars of Metal into I-Iooks, and also into Eyes, such as arecommonly made at a shop withv hammer and anvil; and I do hereby declarethat the following is a full, clear, and exact description of theconstruction and operation of the same, reference being had to theannexed draw ings, making a part of this specification, in which- Figure1 is a perspective view; and

Figures 2, 3, and 4 are views of sectional parts.

The nature of my invention consists ot` a device for bending andformingrods or bars of iron or other metal into the form cf hooks andalso eyes.

In iig. 1, a represents the main frame, resting at either end upon abench, and bearing the reciprocating head-blocks b sliding thereon, bymeans of the two connection-rods e e, attached to the cranks of theshaft CZ, operated by the foot of theoperator on the trip e, causing areciprocating motion to the block b. Two connection-rods are used, asshown in' tig. 1, to give uniformity of motion te either end of thehead-blocks b. f represents a weight attached to the crank g, for thepurpose of sliding the head-block Z) back as soon as the operator liftshis foot from the trip. 7L represents an adjustable former held to itsplace by the thumb-serew z'. The bar of metal is placed between thehead-block Z) and the fermer z, with the outer end touching the gauge j,which is set at any distance so as to regulate the length of the hook oreye. After the bar is so placed the head-block l is moved forward by thefoot on the trip so as te press the rod or bar tightly against theformer,

when the lever 7c is moved around with the friction-roller Z bearingagainst the rod or bar, and bends the same around the nipple m on theend of theformer, thusforming an eye. To form a hook, the former, shownin iig. 4, is used with a right-angle section at the end, around againstwhich the rod or bar is bent, thus forming a hook. The section at theend may be of any angle, to ferm any shaped hook desired. The lever 7cis attached to the head-bleck 6 by means et' the slotted plates n, bothon the upperand under side ofthe same, projecting7 as shown in tig. 1,to meet the lips 0i` the lever 7c, to which they are hinged. By meanset' thumb-screws in the slot in the plates, they may be adjusted so asto place the lever-7c in the right position to bend any sized or lengthred or bar. Figs. 2 and 3 show the nipple and the former' detached.Anysized nipple may be placed in the former to make any sized eye. Itis' designed te bend either het or cold metal.

The particular improvement in this invention consists in being able todispense with the necessity of driving a mandrel in the eye. The nipplem is slightly tapered from the base tothe apex, thus making it easy toremove the eye after it is bent around the nipple.

' Olaz'ms.

What I claim as new in my invention, and desire toY secure by LettersPatent, is-

l. The lever k, with the friction-relier Z, combined with the slottedplates n oz, constructed as and for the purposes described. i

2. I claim the use of the trip c and the weightj' with the crankshaft (Zand the connecting-rods c e, constructed and arranged for the purpose ofoperating the head-block as'deseribed.

8. I claim the adjustable former 7i, in combination with the nipple mand the gauge j.

4. I claim a combination of all the parts described, substantially asand for the purposes set forth.
